2008 DRL relay

On the 2008 F150 on the driver,s fender toward the front there is an auxiliary relay. I have the relay for F150 w/o DRL. For ones with DRL there is another relay (shown in the owners Manuel). This relay is set up for DRL. Does anyone know what would happen if you the relay w/o DRL and replaced it with the one for DRL. The mounting is the same and it looks like it takes the same plug.
Thanks
